## Pumping Lemma

Show that the set $\{0^{2n}1^{n}\}$ is not regular using the pumping lemma.

$\mbox{ is a deterministic finite automaton and if } x \mbox{ is a string in }L(m),$ $\mbox{ the language recognized by M, with }$ $l(x) \geq |S|,$ $\mbox{ then there are strings }u, v, w \mbox{ in } I^{*}$ $\mbox{such that }$ $x = uvw, I(uv) \leq |S| \mbox{ and }l(v) \geq 1,\mbox{ and }uv^{i}w \in L(M) \mbox{ for }i = 0, 1, 2, ...$
